Microcystis genera

Reports on the anti-influenza virus effects of extracts from marine algae from all over the world have been found in the literature [115]. These results show that the blue-green algae (cyanobacterium) are able to produce compounds with anti-influenza activity that may be of potential clinical interest. For example, aqueous and methanolic extracts of cultured cyanobacteria of several genera. Microcystis, Nodularia, Oscillatoria, Scytonema, Lyngbya and Calothrix were evaluated for their in vitro antiviral activity against the influenza A virus in Madin Darby kidney cells [116,117]. The further analysis of methanolic extracts of cultured strains of genus Microcystis revealed a remarkable antiviral... 

Microcystis aeruginosa (order Chroococcales) accounts for 92% of the compounds isolated from the genus Microcystis (49 compounds total) with 6% coming from Microcystis viridis and 2% from undetermined species. However, it is likely that some variants of the microcystin structure were not tallied in our analysis.
